A paper plant is being proposed for a location 1 km upwind from a town. It will emit 40 g/s of hydrogen sulfide, which has an odor threshold of about 0.1 mg/m³. Winds at the stack may vary from 4 to 10 m/s blowing toward the town. What minimum stack height should be used to assure concentrations are nor more than 0.1 times the odor threshold at the near edge of town on a class B day? To be conservative, the stack will be designed assuming no plume rise. If the town extends beyond the 1-km distance, will any buildings experience higher concentrations than a residence at the boundary under these conditions?

Question

A paper plant is being proposed for a location 1 km upwind from a town. It will emit
40 g/s of hydrogen sulfide, which has an odor threshold of about 0.1 mg/m³. Winds at
the stack may vary from 4 to 10 m/s blowing toward the town. What minimum stack
height should be used to assure concentrations are nor more than 0.1 times the odor
threshold at the near edge of town on a class B day? To be conservative, the stack will be
designed assuming no plume rise. If the town extends beyond the 1-km distance, will any
buildings experience higher concentrations than a residence at the boundary under these
conditions?
